LOCK MECHANISM.

To all whom it may concern: 7

Be it known that I, HARRY SEDER, a citizen of the United States, andresiding in the city of Pittsburgh, in the county of Allegheny and Stateof Pennsylvania, have invented or discovered new and useful Improvementsin Look Mechanism, of which the following is a specification.

My invention consists in a new and imprpved lock mechanism for trunks,suit cases, and other containers, and the purpose in view istheprovision of increased security of combining in a novel form of lock thefunctions of both a key lock and a pad lock.

Generally speaking my improved locking mechanism is of the followingconstruction. One portion of the container, usually the lid, is providedwith a pivotally mounted hasp, while the body or other part of thecontainer is provided with a modified spring lock mechanism. The springactuated bolt plate of the lock is provided with a projecting keeperwhich extends through the slot in the hasp and is provided with a notchwhich engages the hasp and prevents its being swung away from thekeeper, unless said keeper is forced aside against the action of thelock spring. When the hasp is swung down over the keeper itautomatically engages said notch. By turning the key in the properdirection, the keeper is locked stationary and cannot release the haspuntil the key is inserted and turned into its unlocked position.

Many novel features of construction and arrangement of parts will appearfrom the following description.

In the accompanying drawings, Figure 1 is a face View showing my lockingmechanism in use and double locked, the pad lock being shown in dottedlines; Fig. 2 is a similar view with the pad lock omitted and the haspand cover plate of the key lock in dotted lines, to better show the lockmecha nism; Fig. 3 is a longitudinal section through the hasp and lock,and Fig. A is a similar view with the hasp and the sliding key holemember omitted for the sake of clearness.

The following is a detailed description of the drawings.

A is the hasp which is hinged to a plate B which may be riveted, as at 1to the lid of a trunk or other container with a hasp A depending. Thehasp is provided with a longitudinal slot 2.

Specification of Letters Patent. ,l atented June 10 1919. Applicationfiled April 1, 1919. Serial No. 286,652.

C is the back plate of the lock riveted, as at 3, to the under side ofthe cover plate D; while said cover plate is riveted or secured, as at4, to the body of the trunk, or other container. The central portion ofthe cover plate D is pressed out to form a compartment with the backplate O within which is assembled the key lock mechanism.

Said key lock mechanism is shown as of the following construction. E isa sliding bolt plate having'its upper end provided with an outwardlyprojecting keeper F which protrudes through a slot 5 in the cover plateD and is provided with a hole '6 for the attachment of a padlock G. 5are guide shoulders on the back plate C to keep the bolt plate E inproper alinement. The cover plate D is provided with a sunken panel 7,extending from its top edge and surrounding the slot 5, into whichdepression the hasp A fits when swung down into place over the keeper F.The lower edge of said keeper is provided near its base with a notch 8which the hasp A engages, the end of the slot 2 of the hasp beingundercut or shouldered, as at 8 to fit into said notch, thus forming asnug interlocking engagement be tween the hasp and the keeper which isconcealed and cannot be forced by a knife blade or other tool.

The bolt plate E is resiliently held depressed, with the hasp A engagedby the notch 8 of the keepeigby means of a folded leaf spring 9interposed between the studs 10 on the bolt plate E and an internalshoulder 11 on the cover plate D formed by the lower end of the panel 7The outer end of the keeper F is rounded, so that, when the hasp A isswung down over the keeper, the latter is forced upwardly, compressingthe spring 9 until the hasp seats in panel 7 when the keeper springsdownwardly with the notch 8 engaging and holding stationary the hasp.Thus the lid is held shut until the bolt plate E is forced upwardlyagainst the spring 9.

The lower portion of the cover plate D is provided with a slot 12through which protrudes the key spindle 13 of the bolt plate E, and H isa key hole plate held against the face of the cover plate D by means ofintegral tongues let which extend down through the slot 12 and are fixedin the bolt plate E. Thus the plate H slides in unison with the boltplate E and said bolt plate may be elevated against the action of thesprin 9, to release the keeper F from the hasp A,I)y pushing the keyhole plate H upwardly with the thumb. ,The key hole plate H registerswith the key spindle 13 so that avkey may be inserted to throw thespring mounted slide I toward the left in Fig. 2 so as to engage thewider side of the projection 15 of the base plate C, thus looking thebolt plate and its keeper against upward movement and thereby preventingthe disengagement of the hasp from the keeper. A reverse movement of thekey will return the slide I back to the position shown in Fig. 2,thereby unlocking the key look so that the bolt plate keeper may beelevated, against the action of the spring 9 to release the hasp.

My improved duplex lockpresents a number of substantial advantages overthe prior art. The hasp and keeper which are used in connection with thepadlock are parts of the key lock mechanism, and therefore I avoid anymaterial inerease of manufacturing cost, and I also am enabled toconfine the looking operation to the center or other selected point onthe lid and body of the container. By using the padlock keeper as thelocking portion of my spring bolt plate, I obtain a more compact and'sightly structure, and in case the lock key is'lost, I may use the padlock for locking the container and the bolt plate for the spring catchused for temporarily holding the container closed without looking. I

, The most usual application of my invention is for the purpose oifloeking traveling or shipping containers, either giving double lockingsecurity 013w enable one form of locking action to be'used when theother form is out of commission, such, for instance,

as through the loss of either the key lock key i or the pad lock key orthe pad lock itsel However, my invention may be applied with greatadvantage to boxes for storing securities or other valuable where thebox is to be opened only with the consentand in the presence of twopersons. Thus both locking actions can be used, the key lock key beingretained by one person while the pad lock key is retained by the other.

What I desire to claim is z 1. In a duplex lock of the characterdescribed, the combination of a spring actu ated sliding keeper,provided with a notch,

for attaching a pad lock to said keeper out- 7 side of said hasp.

3. In a duplex lock of the character described, the combination of aspring actuated bolt plate, a notched keeper carried thereby, a slottedhinged haspl adaptedto be swung down'over said keeper and tofengage saidnotch, means for locking said bolt plate stationary, and means forattaching a pad lock to said keeper outside of said hasp.
